Believing that standard office furniture causes lethargy, designers Clara and Paul created a workspace designed to keep employees alert. The desks are slightly tilted, and the chairs have no backrests, requiring constant balance. The effect is tiring but effective: after six months, workers reported higher focus levels and less afternoon fatigue.
Which choice best states the main idea of the text?
Uncomfortable furniture is the only way to improve worker productivity.
Clara and Paul’s furniture design, though physically demanding, may improve employee focus.
Workers generally prefer tilted desks over flat ones.
The new furniture failed because it made the workers too tired to work.
Correct Answer: B
Choice B is the best answer. The text says the furniture requires balance and is tiring ("disorienting but invigorating" in the original logic). It concludes that workers had higher focus.
Choice A is incorrect. "Only way" is too extreme. Choice C is incorrect. No mention of worker preference, only results. Choice D is incorrect. It says it was effective, not a failure.
